Abstract
Briefly stated, the present invention comprises a resuscitation mask for administering artificial respiration to a patient. The respiration mask has a container for defining an interior region between the container and the face of the patient. Two conduits are provided through the container wall in order to define two air flow passageways which are in fluid communication with the internal region. A valve is disposed in one air flow passageway for permitting air flow into the internal region and preventing air flow from the internal region. A vent is provided to reduce pressure within the internal region in response to an increase in pressure within the internal region. The container is generally cup-shaped and, in the preferred embodiment, it is formed with a cylindrical member coupled to the one-way air flow conduit. The other airflow passageway is adapted to be detachably coupled to an oxygen source. A pressure openable closure permits pressure within the interior region of the resuscitation mask to be released by a further conduit.
